GUSTAV SCHMIDT, OF RHEINE, PRUSSIA, GERMANY.

CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 404,563, dated June 4,1889. Application filed March 11, 1889. Serial Ila-302,812. (N0 model.)

To all whom it may concern.-

Be it known that I, GUSTAV SCHMIDT, of Rheine, in the Kingdom of Prussiaand German Empire, have invented a new and useful Improvement inOar-Starters, of which the following is a specification, reference beinghad to the accompanying drawings.

My invention relates to car-starters, and has for its object to providea car-starter which will be simple in construction and effective inoperation.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a plan view of the car-starter, and Fig. 2 is a side viewthereof. 7

The car-starter is constructed with a base portionA, preferably formedwith the inclined shank A, to bring the lever-handle B at an incline.The lever-handle B preferably consists of awrought-iron tube or pipe forthe sake of lightness, and is secured to the shank A by means of theshouldered end of the latter projecting into the handle B, as shown indotted lines. The base A is formed with the lever-arm 0, provided withthe hardened plate d, preferably formed of cast-steel and projectingfrom end of arm 0, and detachably connected thereto by means of theshank C, located in an open-ended slot (1' in the upper surface of arm0, and secured in place by a set-screw A or other suitable means. Bythis means the plate d may be detached from the base A to avoid exposingthe latter to the fire when the plate d requires repairing orsharpening.

The plate cl, which in using the car-starter is located under the rim ofa car-wheel, must be as hard and sharp as possible, so as not to slip onthe rim of the wheel.

WVithin an opening in the base A is mounted a grooved roller a, providedwith flanges b I), having ratchet-teeth a. By means of the groovedroller a, which is adapted to fit over the crown or head of arailroad-rail, the carstarter can be easily moved on the rail to insertthe plate (1 and arm 0 between the rail and the rim of a car-wheel.

To prevent the roller afrom revolving backward when the load is heavy orthe rails are wet, the roller is held by a pawl c, mounted on aprojection c on the shank A and engaging the ratchet-teeth a of flangeb. A second pawl may be employed, if desired, to engage theratchet-teeth of flange b.

The grooved roller a'is of small diameter to permit it to be pushed asfar as possible under a car-wheel to give the greatest possible effectto the leverage of the car-starter.

The lever-arm is formed at its end with the inclined under side 0 to aidin inserting it between the rail and acar-wheel and assist in theleverage.

The proportion of the two lever-armsz'. 6., the arm 0 and shank A, withhandle B-may be about as one to ten.

By means of this invention a very light, simple, durable, and effectivecar-starter is provided, which secures a strong grip upon the rail,enabling a heavily-laden car to be easily started and propelled.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A car-starter consisting of the base A, with inclinedshank A, pawl 0, mounted thereon, and tubular inclined handle B, the arm0, with detachable plate d, and the grooved roller a, having flanges bb, and ratchet-teeth a on flange b, with which the pawl c engages,substantially as shown and described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

GUSTAV SCHMIDT.
